stem cell

n.
An unspecialized cell that can give rise to one or more different types of specialized cells, such as blood cells and nerve cells. Stem cells are present in embryos and in various tissues of adult organisms and are widely used in scientific research.

(Biology) histology an undifferentiated cell that gives rise to specialized cells, such as blood cells

stem′ cell`


n.
a cell that upon division replaces its own numbers and also gives rise to cells that differentiate further into one or more specialized types.

stem cell

A cell that has the potential to develop into any of a number of different types of cells. Embryos have stem cells that can develop into almost any kind of body cell. Certain tissues in adults also produce stem cells, although the range of cells that they can develop into is limited.

A stem cell is an unspecialized cell that is capable of developing into a specialized cell of the body, such as a skin cell, a blood cell, a muscle cell, or a nerve cell.
Shiwani Moghe, a graduate student at Texas Woman's University, decided to evaluate whether blueberry polyphenols play a role in adipocyte differentiation, the process in which a relatively unspecialized cell acquires specialized features of an adipocyte, an animal connective tissue cell specialized for the synthesis and storage of fat.
Differentiation is a process involving unspecialized cells progressing to become specialized cells with restricted developmental potential.
In nature, embryonic development starts with a mass of unspecialized cells.
The tissue cultures were analyzed for polyphenols' effect on adipocyte differentiation, which is the process by which unspecialized cells acquire the features of adipocytes that synthesize and store fat.
Stem cells are unspecialized cells that are capable of differentiating into any other cell type.
It was also shown that astrocytes can instruct unspecialized cells to become neurons--a process called neurogenesis (Svendsen, 2002).
Nanotubes may also carry a yet unknown heart development signal: They have been observed connecting naive, unspecialized cells to mature heart cells, hinting at a new way cells may find their adult identity.
